Copy Relationhsip BUR001 from a BP Org to another BP Org
I have a question about the Relationship BUR001 (has contact person) where I need you advice. I do have two different Business Partners, BP# 1 and BP# 2 which I identified as dublicates because the Business Partner had been created twice by mistake. The BP#1 has some contact persons (RELTYP BUR001 in BUT050 or BUT051) which are not maintained on the BP#2 which I would like to move from BP#1 to BP#2. I know that I can use the BAPI BUPR_RELATIONSHIP_CHANGE or BUPR_RELATIONSHIP_CREATE for this.
The problem I have by using this BAPIS is the the information which is maintained on the Relationship e.g. the email address or phone number for this contact person does not get moved over to the relationship i create new.
Basically I would need to move a contact person which is created on a BP Org with the RELTYP BUR001 with all information from a business partner A to a business partner B.
Are there any experts who can help me with this?
Thanks a lot.
